i don't really know what's wrong my car. need help asap! my car dies on me when coming to a stop and also my car kind of bog or stutter when hitting full boost. boost seem to drop from 11psi to 8 psi. anyone know what could be wrong.

any help would be great. thanks!!

 

More info on the setup please.

Is it tuned?

 

engine managment? is it tuned x2? Any cels?

alot more info

 

hondata s200
fully built block with which is not tune but the head is. the head was tune with the old gsr block now i have a dart block with same mod like the old block.

 

okay took car for a spin and the rattle noise by the wastegate and turbo is getting louder and the engine seems to get really hot and still dies on me when coming to a stop. when warming up the car it seems like it's about to die but starts back up. anyone know what's wrong? will have a clip of the noise and what i mean tomorrow.

 

Ok I am going to help you while putting on my flame suit... just because the motor was tuned before doesnt mean that if you change the motor the car remains tuned. Each motor/part is different and needs tuning. I am positive that if you get that car tuned your problems would probably go away.

ps you cant tune a head you tune the entire motor/setup... stop driving the car and get it tuned

 

yeah been trying to find a tuner around the nashville, tn area but no luck. yeah im hoping the car just need to be tune.

 

everytime i rev the air fuel gauge will go pass 18 then will bog up on me and shut off

 

anyone??

my vtec oil pressure switch is not connected cause the wires came apart. could that be the problem??

 

I'm going to go ahead and say that your running lean, and probably doing alot of damage to your new parts. stop driving it ASAP. the reason your motor is getting so hot is because of your lean conditions. that's not good at all. new parts can melt or break just like OEM parts. it's not bulletproof.

 

You need to tune the motor! at least get a ecu with a base map burned for your setup if your gonna drive on it!

So your running a untuned motor, running afr's in the 18's, and you dont have vtec engaged so the upper rpms are running like ****. Dude park the thing until its tuned before your pulling the motor again.

 

This is what you need to do, grab your keys go find one of your parents or friends and give them the keys and tell them not to let you have them...HOT=NOT GOOD ..

Sorry to be a dick but everyone told you right away to get the car tuned, but you keep driving it around and wondering what is wrong

 

well taking the car to mainstream performance down in georgia to get it tune so hopefully my car will be back to normal. *anyone know a closer place to get it tune in the tn or ky area* don't really want to trailer my car all the way to ga if i can find a honda freak tuner in the tn and ky area. im in the military so kind of want to stay in the 250 miles range.

 

Do you actually have an ECU with s200 on it, or you just yanking our chains? You can't just "tune your head", the whole motor needs to be tuned. Stop driving it, throw your keys under your bed and go get it tuned.

 

yes i have an ecu with hondata s200. i didn't just tune my head. the head that is on my built dart block right now use to be on my old built gsr block which was tune and made 540hp on 24lbs of boost on c16 and 340hp on 11lbs on pump gas. the old built gsr block went out on me so i purchase the dart block and built it. the new block and the old head was never tune that's why i said only the head was tune.
